American teacher who was chosen to be the first private citizen in space. Aboard the space shuttle Challenger, she was one of the seven astronauts killed when the rocket exploded 73 seconds after takeoff. The death of McAuliffe and her fellow crew members in the 1986 space shuttle Challenger disaster was deeply felt by the nation and had a strong effect on the U.S. space program. Space shuttle flights were suspended until 1988. An independent U.S. commission blamed the disaster on unusually cold temperatures that morning and the failure of the O-rings, a set of gaskets in the rocket boosters.

French mathematician who was awarded the Fields Medal in 1958 for his work in topology, in particular on characteristic classes, cobordism theory and the Thom transversality theorem. Thom is also known for his later work developing the catastrophe theory (1972), a mathematical treatment of continuous action producing a discontinuous result. Thom's theory is an attempt to describe, in a way that is impossible using differential calculus, those situations in which gradually changing forces lead to so-called catastrophes, or abrupt changes. The theory has widespread application in the physical and biological sciences and in the social sciences, but eventually fell from favour.

Russian astronomer who claimed to have discovered volcano-like activity on the Moon. His sightings of apparent gaseous emissions from the lunar surface challenged the long-held theory that the Moon is a dead and inert celestial body. For years, amateur astronomers have reported seeing strange colors on the moon, especially in the Alphonsus and Aristarchus regions. These types of observations gained credibility when on 13 Nov 1958, Kozyrev saw a brightening at the central peak in the crater Alphonsus. He photographed its spectrum, which showed carbon-vapor emissions.

French mathematician who is known chiefly for his contribution to real analysis. He is credited with being the founder of the theory of abstract spaces, which generalized the traditional mathematical definition of space as a locus for the comparison of figures; in Fréchet's terms, space is defined as a set of points and the set of relations. In his dissertation of 1906, he investigated functionals on a metric space and formulated the abstract notion of compactness. In 1907, he discovered an integral representation theorem for functionals on the space of quadratic Lebesgue integrable functions. He also made important contributions to statistics, probability and calculus.

English chemist and physicist who received the Nobel Prize for Chemistry in 1921 for investigating radioactive substances. He suggested that different elements produced in different radioactive transformations were capable of occupying the same place on the Periodic Table, and on 18 Feb 1913 he named such species “isotopes” from Greek words meaning “same place.” He is credited, along with others, with the discovery of the element protactinium in 1917.

French scientist, known for his invention of smokeless powder. Military commanders since the Napoleonic Wars had problems giving orders on a battlefield swathed in thick smoke from the gunpowder used by the guns. In 1886 Paul Vieille invented a smokeless gunpowder called Poudre B. Made from gelatinized nitrocellulose mixed with ether and alcohol, it was passed through rollers to form thin sheets, which were cut with a guillotine to flakes of the desired size. It revolutionized the effectiveness of small guns and rifles.It was much more powerful than gun powder, giving an accurate rifle range of up to 1000 yards.

German archaeologist and historian who directed the excavation of Olympia from 1875-1881, the most opulent and sacred religious shrine of ancient Greece and site of the original Olympic Games (from 776 B.C. to 393 A.D.). The excavations cleared the whole of the sacred precinct and some buildings that lay outside it. The position of the stadium was located by exploratory trenches. Thus the plan of a great Greek sanctuary was revealed for the first time. The excavation also unearthed the only major surviving sculpture by Praxiteles, “Hermes Carrying the young Dionysus” found in the cella of the temple in 1877, now one of the most prized possessions of the Olympia Museum. more

Frank Donald Drake was an American astronomer and astrophysicist who formulated the Drake Equation (1961) to estimate the number of technological civilizations that may exist in the Milky Way galaxy, N = R* × fp × ne× fl × fi × fc × L. Using plausible guesses for the parameters, Drake concluded perhaps 10 planets in our galaxy may have life originating detectable signals. In 1960, Drake led the first search, the two-month Project Ozma to listen for patterns in radio waves with a complex, ordered pattern that might be assumed to represent messages from some extraterrestrial intelligence. Carl Sagan and Drake designed the plaques on Pioneer 10 and Pioneer 11 for the purpose of greeting and informing any extraterrestrial life that might find the vessels after they left the solar system.

Christiaan Neethling Barnard was a South African surgeon who performed the world’s first human heart transplant operation. In a five-hour operation on 3 Dec 1967, Barnard successfully replaced the diseased heart of Louis Washkansky (55) with a healthy heart from Denise Darvall, a woman in her mid-20s with the same blood type, who died in hospital after an automobile accident. Barnard knew it was a surgical success when he first applied electrodes and the heart resumed beating. Washkansky died 18 days later of double pneumonia as a result of his suppressed immune system. It was a milestone, however, in a new field of life-extending surgery. Rheumatoid arthritis and advancing stiffness in his hands forced his retirement from surgery in 1983.

Swedish co-inventor of the Silva compass designed with a compass capsule filled with a motion-damping fluid, a rotating compass dial, and a transparent protractor baseplate. He helped develop it (1932), with his brothers Alvar and Alvid Kjellstrom, and Gunnar Tillander. Bjorn moved to the U.S., and founded Silva, Inc. in LaPorte, Indiana (1946). He also started Silva Ltd., Toronto, Canada (1948). Kjellstrom helped introduce the orienteering sport to the U.S. (1946), in part as a way to promote his product. He wrote Be Expert with Map and Compass (1955). It has been called the “bible of orienteering.” A publicity slogan used was: “Read this or get lost.” He co-founded the U.S. Orienteering Federation in 1971.«

Irish mathematician in the fields of optics, geometrics, and classical mechanics. By age 12, Hamilton had already learned fourteen languages when he met the American, Zerah Colburn, who could perform amazing mental arithmetical feats, and they joined in competitions. It appears that losing to Colburn sparked Hamilton's interest in mathematics. At 15, he began studied the works of LaPlace and Newton so by age 17 had become the greatest living mathematician. He contributed to the development of optics, dynamics, and algebra. His invention of the calculus of quaternions enabled a three-dimensional algebra or geometry which provided a basis for the later development of quantum mechanics.

English physician and chemist who in 1803 proposed what is now called Henry's law, which states that the mass of a gas dissolved by a given volume of a solvent, at a constant temperature, is directly proportional to the pressure of the gas above the liquid, provided that no chemical action occurs. The law holds well only for slightly soluble gases at low pressure. Henry was a close friend of John Dalton, but despite superior skill and range as an experimenter, lacked Dalton's boldness as a theorist, and Henry never committed himself to the atomic theory. Henry was the third and most successful son of Thomas Henry, an industrial chemist. William was injured by a falling beam at age 10. Those injuries gave him ill health and pain through life; he died by suicide.Do not confuse with physicist, Sir William Henry OF Bragg = William Bragg(1862-1942).

(baron) German-Hungarian astronomer patronized by Duke Ernst of Saxe-Gotha-Altenburg. Director of observatory near Gotha (1787-1806). There he organized in 1798 the first congress of astronomers with Josef Lalande (1732-1807) as celebrated guest. In last years of the 18th century he formed a group of 24 astronomers chosen from throughout Europe to track down a "missing" planet between the orbits of Mars and Jupiter, where they instead discovered the asteroids. His greatest contribution was in the organizational area, for he maintained an enormous correspondence with all the astronomers of his time, and edited 28 volumes of Monatliche Korrespondenz zur Beforderung der Erd- und Himmelskunde (1800-13).

In 1736, Bliss became rector of St Ebbe's Oxford, and in 1742, he followed Edmond Halley as Savilian Professor of Geometry. Bliss occasionally assisted James Bradley, third A.R. In 1761, he made observations of the transit of Venus when Bradley was unable to do so due to poor health. Bliss succeeded Bradley in 1762. On 1 Apr 1764 Bliss published his observations of the annular eclipse visible from Greenwich. Besides his Observatory work, Bliss also worked for and with the Earl of Macclesfield, on astronomical problems. This work included making meridian observations of a comet approaching the Sun around 1744 at Shirburn Castle and at Greenwich.

In 1752, today was the last day of the Julian calendar in Great Britain, Ireland and the British colonies, including those on the East coast of America. Eleven days were skipped to adopt the Gregorian calendar, designed to realign the calendar with equinoxes. Hence the following day was 14 Sep. For more than a century and a half before, following the decree by Pope Gregory XIII, Italy, and three other Catholic countries (Spain, Portugal and Poland) used the Julian calendar for the last time on 4 Oct 1582. France followed, ending Julian calendar use on 9 Dec 1582. Russia did not change until the early 20th century: 31 Jan 1918 was the last Julian date, followed the next day by 14 Feb 1918. Parts of China changed in 1912, but the Communist revolution, 1949, established Gregorian calendar use in all China.«
